Therefore, when the user measures the blood flow using the measuring device 10, the laser light emitted from the side surface 30b is not easily emitted toward the face of the user who performs the operation while viewing the surface 30a. Further, the user can bring the test site into contact with the contact portion 15 while directing the surface 30a in his / her direction based on the guide 40. Therefore, according to the measuring apparatus 10, safety can be improved.
  • the position of the contact portion 15 is not limited to the position shown in FIG.
  • the contact portion 15 is on a surface different from the surface 30a of the measuring device 10 and can be arranged at any position where the user can cover the measuring device 10 with a finger pad without feeling uncomfortable.
  • the contact part 15 can be disposed on another side of the side surface 30b of the measuring apparatus 10, or on another side or back surface other than the side surface 30b. The user may measure the biological information by bringing the contact unit 15 into contact with a finger other than the thumb.
  • the contact part 15 with which the measuring apparatus 10 is provided is not restricted to one.
  • the measuring apparatus 10 may include two or more contact parts.
  • the measurement device 10 in addition to the position shown as the contact portion 15 in FIG. 1, the measurement device 10 is on, for example, a side surface facing the contact portion 15 in FIG. 1, and the contact portion 15 when the measurement device 10 is viewed from the surface 30 a.
  • Another contact portion may be provided at a position that is symmetrical to the right and left.
  • the measuring apparatus 10 includes a guide that indicates the position of each of the plurality of contact portions.
  • the plurality of contact portions are each connected to a pressure detection portion. In this case, the user can bring the thumb into contact with either the left or right contact portion even if the measurement device 10 is held with either left or right hand.
  • the control part 17 inject
  • the control part 17 can prevent that a laser beam is inject
  • the control unit 17 performs the laser beam emission control based on whether the laser beam emission direction is equal to or greater than a predetermined angle with respect to the vertical upward direction.
  • the reference of the angle is not limited to the vertically upward direction.
  • the control unit 17 determines whether or not the laser light emission direction is equal to or greater than a predetermined angle with respect to the vertical downward direction. Based on this, laser light emission control may be performed.
